My invention relates to an anchoring device. It has to do, more particularly, with an anchor"- ing device adapted to be embedded in concrete ceilings and walls and by means of which various members may be attached to or suspended therefrom.

In the past, several different types of anchoring devices of the general class indicated above have been provided. However, most of the devices are possessed of certain undesirable features. One of the greatest disadvantages of these prior art devices resides in the fact that they are of such a structure that it is difiicult to attach hanger or suspending members thereto. They usually require special nuts of various sizes and shapes. Furthermore, these prior art devices are usually of such a structure that there is danger of the hanger or suspending members becoming displaced accidentally from the anchoring device. Also they do not readily permit the use of hangers of different sizes. These prior art devices have also been possessed of certain other undesirable features.

One of the objects of my invention is to provide an extremely simple anchoring device of the type indicated which will be very inexpensive but which will be very effective for the purposes for which it is to be used.

Another object of my invention is to provide an anchoring device of the type indicated which is of such a nature that a hanger or suspending member may be readily attached thereto. g

Another object of my invention is to provide an anchoring device and a cooperating suspending or hanger member which cooperate with each other in such a manner that there will be no danger of the hanger member being accidentally withdrawn from the anchoring device.

Another object of my invention is to provide an anchoring device of the type indicated which is of such a structure that it will be anchored firmly in the concrete.

Various other objects will be apparent from the following description.

The preferred embodiment of my invention is illustrated in the accompanying drawing wherein similar characters of reference designate corresponding parts and wherein:

Figure l is a longitudinal section of the anchoring device and showing the upper portion of a suspending hook therein.

Figure 2 is an end view of the anchoring device embedded in the concrete and attached to the form before the form has been removed.

Figure 3 is a perspective view of the anchoring device and showing how the suspending hook may be inserted therein.

Figure 4 is a perspective view illustrating how my device may be used. c

Figure 5 is a side view of the anchoring device and suspending hook and illustrating how a pipe hanger may be provided on the lower end of the hook.

Figure 6 is a side view showing a difierent type of hanger. With reference to the drawing and particularly to Figures 1, 2 and 3, I have illustrated my anchoring device as comprising a body portion l which may be of cast iron. This body portion l is of elongated hollow construction. It has closed curved ends 2 and has a flat inner wall 3. At its outer edge it has a reinforcing rib or peripheral flange The outer side of the body portion is open with the exception of a transversely extending anchoring rib 5 which is formed intermediate the ends of the body portion and integral therewith. The rib 5 is so located and of such a shape that openings 5 and l are formed in the outer side of my device. The opening 7 is of elongated or slot form while the opening 6 At opposite sides of the body portion, substantially midway between the ends thereof, are formed lugs 9. These lugs are formed integral with the flange 3 and lie in the same plane. Each lug is provided with an open-ended slot or notch ll At its inner corners the body portion l is provided with integral anchoring fingers ii. These fingers extend at an angle to the inner wall 3, as indicated. It will be noted that the end walls and side wall surfaces of the body portion l taper inwardly so that the body portion is of gradually decreasing cross-section from its inner side to its outer side. When the device is embedded in concrete, this will result in a firm anchorage of it in the concrete.

When using this device, assuming that it is to be embedded in a ceiling, the device is first I fastened in a predetermined position to the top surface of a concrete form it. To do this it is merely necessary to rest the device on the form, as illustrated in Figure 2, and pass nails i3 through the slots II] in the lugs 9. Then, concrete may be poured around the device. When this is done and the concrete sets, the device will be securely anchored therein because of anchoring member II and because of the taper of the til body portion. When the form i2 is removed, the device will be embedded in the concrete with its outer surfaces flush with the outer surface of the concrete, as indicated in Figure l.

The embedded anchoring device may then be employed for suspending members therefrom. In doing" this I prefer to employ a hook suspend ing member of the type illustrated in the drawing. The suspending member I4 shown in the drawing has a hook portion l5 formed on its upper end. This hook portion I5 is adapted to be inserted in the device and to be hooked around the rib 5.

As previously stated, the opening I is elongated and larger than the opening 6. This is to permit insertion of the hook portion i5 into the device. To do this the hook member must be turned in the manner illustrated by the full lines in Figure 3 with the body portion thereof parallel to the ceiling. The end of the hook portion 25 is then passed upwardly through opening 7 and the hook may then be swung around to the position indicated in Figure 1 and by the dotted lines in Figure 3, with its one end extending down through the opening 8. It will be noted from Figure 1 that the hook portion 55 is of such a size that if the hook is moved bodily upwardly perpendicular to the inner wall 3, when it contacts with such wall, the end of the hook will still extend into the opening 6, as indicated by the dotted lines. This will prevent accidental displacement or the hook from the anchoring device. To remove the hook it will be necessary to actually turn it so that it can be slipped into the opening The lower end of the hook it may be threaded and a ring member It may be screwed thereon, as indicated in Figure 5. A pipe may be supported from the ceiling, as indicated in Figure 4, by passing it through a plurality of these rings supported by a plurality of my anchoring devices. When the ring member i6 is being screwed on the hook M, rotation of the hook in the anchoring devicewill be precluded due to the structure of the anchoring device. Expansion and con-- traction of the pipe will be permitted without distortion of the members M, since the hooks may pivot about the anchoring ribs 5 of my device. Instead of using rings It, the lower end of the hook member M may be provided with another hook portion hid in which the pipe may rest. Hooks of varying cross-section may be used with my device. Special nuts will not be required and the hangers may be applied easily to my device.

It will be apparent from the above description that my device has many advantages. A number of these advantages have been specifically referred to herein and others will be apparent.

Having thus described my invention, what I claim is:

1. An anchoring device of the type described composed of cast iron and comprising a hollow body portion, said device being adapted to be embedded in concrete with its outer surface flush with the surface of the concrete, said hollow body portion having its inner side closed by a substantially fiat wall and having end and side walls, the end and side walls tapering inwardly, towards the center or" said body portion, said hollow body portion having a rib formed at its outer side intermediate the ends of said body portion and extending transversely, said rib being so disposed and of such shape that two openings are formed in the outer side of said hollow body portion, one of said openings being elongated and the other circular, said body portion having a peripheral, reinforcing flange on its outer edge, the flange and the rib being flush with each other, a pair of oppositely disposed lugs formed as a part of said flange intermediate the ends of said body portion, said lugs being provided with openings through which nails or other similar means may be passed, and outwardly projecting anchoring members formed on said body portion.

2. An anchoring device of, the type described comprising a hollow body portion, said hollow body portion having its inner side closed by a substantially fiat wall and having end and side walls which taper inwardly towards the center of said body portion so that said body portion decreases in cross-sectional area from its inner side to its outer side, said hollow body portion having a rib formed at its outer side intermediate the ends of said body portion and extending transversely, said rib being so disposed and of such shape that two openings are formed in the outer side of said hollow body portion, one of which. is elongated, oppositely disposed lugs formed on said body portion intermediate the ends of said body portion, said lugs being provided with openings through which fastening members may be passed for attaching said anchoring device to the inner surface of a concrete form.

3. An anchoring device of the type described comprising a hollow body portion, said hollow body portion having its inner side closed and hav ing end and side walls which taper inwardly towards the center of said body portion so that said body portion decreases in cross-sectional area from its inner side to its outer side, said body portion having a rib formed at its outer side intermediate the ends of said body portion and extending transversely, said rib being so disposed and of such shape that two openings are formed in the outer side or" said body portion, one of which is elongated.
